Tmux is a great alternative to gnu screen. I can’t believe I’ve never posted my custom Tmux config for Cygwin after all the work I put into it years ago. So here it is. Its features include:

• Uses ctrl+a, like gnu screen, instead of ctrl+b
• Mouse interaction is enabled
• Tab bar/windows:
  • Current tab is highlighted in cyan
  • Cycle through tabbed windows with a click on its tab or ctrl+arrowkeys
  • Reorder tabbed windows with a drag of its tab or alt+arrowkeys
  • ctrl+a,/ to rename a tab on the tab bar
  • Create new window with ctrl+a,c
• Panes
  • Create split panes with vertical=ctrl+a,| and horizontal=ctrl+a,-
  • Move around panes with click or ctrl+shift+arrowkeys
  • Resize panes by dragging on the separator bar or use ctrl+shift+alt+arrowkeys
  • Panes automatically resize to fit OS window
• Clipboard/highlighting
  • Copy text to clipboard by highlighting it. Had to use a minor hack to fix a cygwin selection problem
  • Paste from clipboard with right click
  • Middle mouse button+drag starts copy mode
    • When in copy mode, u runs the selection as a command in a separate window (Instead of “cygstart” for cygwin, use “xdg-open” for linux, or “open” for MacOS X)
  • Double click selects word
  • Double middle click runs the word under the mouse as a command
• Start the session on the current bash directory
• Escape time is lowered for quicker response to scroll buffer access (ctrl+a,pageup)

To use this, save the file to ~/.tmux.conf

Originally posted on: 09/24/19

I recently decided to swap around my hard drives to different SATA slots so my most used hard drives were on the fastest ports. Unfortunately, when I did this, my computer stopped booting to Windows. I never did figure out why my bootable EFI partitions only showed up randomly in BIOS depending on which hard drives were plugged in, but I found a configuration the computer liked and I was able to see the Microsoft Boot EFI partition and EFI boots on my USB keys.

The next step was to get the computer actually booting to something I could run commands on. When I try to boot directly to the EFI shell, the resolution is always screwed up and I can only see the top half of what should be visible, so I can’t actually see the command line I am typing too. This actually happens to everything I directly boot to that uses console text. The way around this for me is that I need to boot to the BIOS setup, and from there tell it to boot immediately to the EFI option of my choice when exiting the BIOS. From there, the proper resolution is used and everything is visible.

Next, in the EFI shell, you can run map to see all of the available possible mounts. This should automatically run when the EFI shell starts anyways, so you should already have that information. Any detected EFI partition on any bootable device should be given a mapping of “fs#” where # is a number. In my case, it was fs0. So to mount that, I ran mount fs0 x. “x” could be whatever you want, it doesn’t really matter. It’s analogous to a drive letter in windows, and you can make it any string (within reason, I believe anything alphanumeric should be fine). So next you would run x: to switch to that drive. From there, you can run cd EFI\Microsoft\Boot and then bootmgfw.efi to boot to windows.

Since I use VeraCrypt system encryption, I had to go to “EFI\VeraCrypt” and run DcsBoot.efi to finally boot into Windows through VeraCrypt.

Finally, to get the Windows Boot manager to start with VeraCrypt, run in the Windows command prompt bcdedit /set '{bootmgr}' path \EFI\VeraCrypt\DcsBoot.efi.

I recently tried to install Slackware 4.2 64-bit (Linux) onto a new mini PC I just bought. The new PC only supports UEFI so I had major issues getting the darn setup on the install cd to actually run. I never DID actually get the install cd to boot properly on the system, so I used an alternative. While the slack install usb key was in, I also added and loaded up an ubuntu live cd usb key. The following is what I used to run the slackware setup in Ubuntu.

#Login as root
#sudo su

#Settings
InstallDVDName=SlackDVD #This is whatever you named your slackware usb key

#/mnt will contain the new file system for running the setup
cd /mnt

#Extract the initrd.img from the slackware dvd into /mnt
cat /media/ubuntu/$InstallDVDName/isolinux/initrd.img | gzip -d | cpio -i

#Bind special linux directories into the /mnt folder
for i in proc sys dev tmp; do mount -o bind /$i ./$i; done

#Mount the cdrom folder into /mnt/cdrom
rm cdrom
mount -o bind /media/ubuntu/$InstallDVDName/ ./cdrom

#Set /mnt as our actaul (ch)root
chroot .

#Run the slackware setup

#NOTE: When installing, your package source directory is at /cdrom/slackware64

It’s a bit of a pain reading results from batch requests to Mailchimp. Here is a quick and dirty bash script to get and pretty print the JSON output. It could be cleaned up a little, including combining some of the commands, but meh.

#Example variables
BATCHID=abc1234567;

#Get the URL to the response
grep -oP '"response_body_url":"https:.*?"' | \
grep -oP 'https:[^"]*' | \

#Get the response
xargs wget -O - 2> /dev/null | \

#The response is a .tar.gz file with a single file in it. So get the contents of this file
tar -xzvO 2> /dev/null | \

#Pretty print the json of the full return and the “response” objects within
php -r '$Response=json_decode(file_get_contents("php://stdin"), true); foreach($Response as &$R) $R["response"]=json_decode($R["response"], true); print json_encode($Response, JSON_PRETTY_PRINT);'

Originally posted on: 04/09/19

Part of my workstation’s audio setup uses the RME Babyface Pro. Until the most recent update of their software, the built-in Window’s sound’s master volume for the device was ignored. So while this script isn’t as important as before, I still find it very useful. So the following is an AutoHotkey script which modifies the master volume in the TotalMix FX window via the mousewheel (when alt+ctrl is held down). This expects the TotalMix FX window to be sized as small as it can, and to have a channel selected for the control room’s Main Out. It should look like this:

The script is as follows:

;Function to create lparam/wparam for SendMessage
CalculatePARAM(w1, w2)
{
   IfLess, w1, 0
      w1 := 65535 + w1 + 1
   IfLess, w2, 0
      w2 := 65535 + w2 + 1

   return (w2<<16 | w1)
}

;Send a mouse wheel action to a window
SendMouseWheel(WindowHWND, Steps, XPos, YPos)
{
   ;Constants
   WM_MOUSEWHEEL := 0x20A
   WheelStepAmount := 120

   ;Calculate and execute the message
   WinGetPos, ScreenX, ScreenY,,, ahk_id %WindowHWND%
   wparam := CalculatePARAM(0, Steps*WheelStepAmount)
   lparam := CalculatePARAM(XPos+ScreenX, YPos+ScreenY)
   SendMessage, %WM_MOUSEWHEEL%, %wparam%, %lparam%,, ahk_id %WindowHWND%
}

^!WheelUp::
ControlGet, ControlHWND, Hwnd,,AfxFrameOrView100s1,RME TotalMix
if ControlHWND
   SendMouseWheel(ControlHWND, 1, 36, 428)
return

Hi @Dakusan

I have come back to your script/.exe because Plex threw away one of my previously imported m3u Playlists.Im getting this error:
PlexPlaylistImporter.exe -p "D:\PlexServer\Plex Media Server\Plug-in Support\Databases\com.plexapp.plugins.library.db" "D:\7mc\plexplaylistimporter\top 550 songs.m3u" Top550SongsPlex playlist is not already created. Would you like to create it now (y/n)? y
DB Error: no such collation sequence: naturalsort

This is on Windows 10 x64, on the Plex Server console.  The exe worked really hard for about 10 minutes before coming up with the playlist creation question, and then immediately failed with the error.Any ideas on that one?

[Create the new boot entry]

Original post for Auto Locking Windows on Login can be found at https://www.castledragmire.com/Posts/Auto_Locking_Windows_on_Login.
Originally posted on: 12/07/18

On my primary computer (whose harddrive is encrypted) I always have Windows auto logging in to help with the bootup time. However, my bootup time can be rather slow; and if I needed to have my computer booted but locked, I had to wait for the login to complete so I could lock the computer. This has been becoming a nuisance lately when I need to get out of my house quickly in the morning.

For the solution I created a windows boot entry that auto locks the computer after logging the user in. This also requires a batch file, to run for the user on startup, to detect when this boot entry was selected. Here are the steps to create this setup:

1. Create the new boot entry:In the windows command line, run: bcdedit /copy {current} /d "Lock on Startup"
   This creates a new boot option, duplicated from your currently selected boot option, in the boot menu labeled “Lock on Startup”.
2. (Optional) Change the bootup timeout:In the windows command line, run: bcdedit /timeout 5
   Where 5 is a 5 second timeout.
3. Create a batch file to run on login:In your start menu’s startup folder, add a batch file. You can name it anything as long as the extension is “.bat”.
   Add the following to the file: bcdedit /enum {current} | findstr /r /c:"description  *Lock on Startup" && rundll32.exe user32.dll,LockWorkStation
   Note that there are 2 spaces in the description search string to replicate the regular expression's 1 or more quantifier “+”, since findstr only supports the 0 or more quantifier “*”.

It is not possible with the program, and would not be easy if the image size was different than the original.

However, if I recall (this project is almost 15 years old, so I could be remembering wrong) they are stored in 24bit uncompressed bitmap format in the container file, so if you search with a hex editor in the original file for a byte string from the extracted picture, you can find it, and replace it with another bitmap of the same size.

If it isn't stored in 24bit uncompressed format, the extracted images will probably still be the same as the original in the container file and you can still search for them in there with a hex editor. And as long as you replace it with a bitmap of equal or less size, it should work.

When replacing, make sure to replace the entire bitmap file in the container, including the bitmap header.
